SOURCE: gas cap is contacting inside of filler neck

SOURCE: my camry's check engine light came on and the

The EVAP system on OBD-II equipped vehicles is monitored by the computer. When the gas cap is bad, or if there is a break in the system somewhere, this alerts the computer (ECU) of a problem and the ECU will turn on the check engine light to alert you of a problem. Although not normal, it is something that can happen and need replacement. You can inspect the filler neck yourself for visible damage (it is the flexible/ribbed hose going into your fuel tank from the filler) and replace the gas cap yourself. i might suggest replacing the gas cap and then having an Auto Zone or Napa reset your computer to see if the cap was the extent of the problem before i paid a shop to replace the filler neck. If the cap was specified as a problem, you really have nothing to lose on pursuing this fix first. Also, if you can order the filler neck, this is a relatively easy replacement and requires only shadetree mechanic skills.

i hope this helps,
matthew

Toyota echo check engine gas cap


In my wife's case it was that the neck of the filler (where it contacts the gas cap) rusted. It didn't allow a good seal. Since it was a 2005 we also replaced the gas cap in 2013.

Fuel filler neck


Clean off the rust

The Check Light doesn't mean the
filler neck is the issue, unless you got
a code for a small Evap Leak & then
it could be any of 10 things & maybe
a bad gas cap

GMC Jimmy gas filler neck leak


Replace your filler neck. It's not hard and when you buy the new one, installation should be obvious and rather straight forward.

A fuel leak is not something to take lightly and it will get worse over time.

Most fuel systems are pressurized (that's why you'll sometimes hear a hissing sound when you open your cap) so if your filler neck is leaking it can throw a code.

My service engine soon light was on. I took the vehicle to a mechanic and the code came back po422. A smoke check was performed and they said it had a leak in the filler neck and the entire gas tank needed...


If they forgot to tighten the hose clamps on the hose from the tank to the filler cap it could be setting it off. If they are all tight it was probably just the gas cap. The gas cap is usually ALWAYS the culprit. Let me know if this helps

Emission System light is on


Check the fuel filler neck where you put the gas in sometimes the liner inside of the filler neck at the top where the gas cap is gets hair line cracks. Also check and or replace the gas cap.
